This rare mosaic, the earliest known image of Christ in Britain, comes from the center of a mosaic pavement in a 4th-century Roman villa. It was discovered in the village of Hinton St Mary (Dorset) in 1963. It is the only known portrait of Christ used in a mosaic pavement. Instead of a halo there is a Chi-Rho (first two letters of Christ in Greek) monogram behind his head. The pomegranates symbolize resurrection. British Museum, London. Credit: Holly Hayes.
